TECHNICAL FIELD

Embodiments of the present invention relate generally to printing services, and more particularly provide systems and methods for printing documents.

BACKGROUND

Printing electronic documents stored on network servers is a common task, especially in work environments. In current systems, a user typically initiates a print request from a work computer. The print request identifies the electronic document and the connected printer. In response, the work computer generates a printable representation of the electronic document and displays a print preview. The user can modify print configuration settings and view a new print preview of the electronic document. The user can then launch the print job to the printer. The work computer forwards the printable representation of the electronic document through the network to the printer, which prints the printable representation. The user then goes to the printer to obtain the hardcopy of the printable representation.

U.S. patent application Ser. No. 13/363,336, filed Jan. 31, 2012 and entitled “Printing an Electronic Document Using a Printer and a Mobile Device,” discloses a method for printing an electronic document using a printer and a mobile device. The printer receives a request to print. The printer generates a unique identifier in response to the request. The mobile device sends a print job associated with the unique identifier and the electronic document to a print server over a network. The printer sends the unique identifier to the print server. The printer receives the print job from the print server in response to sending the unique identifier, and prints a hardcopy of the electronic document based on the print job.

Systems and methods that are capable of more efficiently printing a network document would be helpful.

DETAILED DESCRIPTION

The following description is provided to enable a person skilled in the art to make and use various embodiments of the invention. Modifications are possible. The generic principles defined herein may be applied to the disclosed and other embodiments without departing from the spirit and scope of the invention. Thus, the claims are not intended to be limited to the embodiments disclosed, but are to be accorded the widest scope consistent with the principles, features and teachings herein.

In accordance with some embodiments of the present invention, a printing system generates a graphical code image (e.g., dimensional barcodes, dimensional matrix barcodes (such as quick response [QR] codes), alphanumeric characters, and/or any other optical machine-readable representation of data) representing a document identifier (e.g., a document name, a URL, a storage location, a memory location, hash information, an alphanumeric identifier, etc.). The printing system uses graphical code images to transfer document identifiers between mobile devices and image forming apparatuses to identify documents on a server device, e.g., in data storage or a print queue, for printing.

In some embodiments, the user can transfer a particular graphical code image associated with the desired document from one of the mobile computing device or the image forming apparatus to the other. The receiving device can give the graphical code image or the document identifier represented thereby to the server device to enable the server device to locate the desired document. The desired document can be converted into a printable representation. The user can review a print preview of the document on the mobile device, and change configuration settings. The image forming apparatus can print the document.

In some embodiments, the user can provide the graphical code image to the image forming apparatus using a scanner on the image forming apparatus. The image forming apparatus can provide the graphical code image or the document identifier represented thereby to the server device to identify and request the document for printing.

In some embodiments, after a user logs onto the image forming apparatus, the image forming apparatus displays a list of document descriptors of documents that the user is permitted to access (e.g., print jobs located in the queue that are associated with the user) and allows the user to identify a desired document for printing from the list. The document descriptors may be or include the graphical code images. The user uses a mobile computing device to capture a snapshot of the graphical code image associated with the desired document (e.g., using a camera on the mobile computing device). The mobile computing device provides the graphical code image or the document identifier represented thereby to the server device to identify the desired document. The desired document is retrieved from the server device and converted into a printable representation. The server device forwards the document to the mobile computing device. The user can review a print preview of the document, and change configuration settings. After the printable representation of the document is finalized, the document (possibly in a printable representation) is provided to the image forming apparatus for printing.

In some embodiments, the mobile computing device displays a list of document descriptors of documents that the user is permitted to access (e.g., print jobs located in the queue that are associated with the user) and allows the user to identify a desired document for printing from the list. The document descriptors may be or include the graphical code images. In response to selection of the desired document, the mobile computing device displays the graphical code image. The image forming apparatus scans the graphical code image, and provides the graphical code image or the document identifier represented thereby to the server device. The desired document is retrieved from the server device and converted into a printable representation. The server device forwards the document to the image forming apparatus. The user can review a print preview of the document, and change configuration settings. After the printable representation of the document is finalized, the image forming apparatus prints the document.

In some embodiments, the printing system prevents the image forming apparatus from directly accessing documents associated with the user to decrease potential security concerns.

FIG. 7 is a flow diagram illustrating a method 700 of printing a network document, in accordance with a first embodiment of the present invention. Although the method 700 is shown as presenting a list of graphical code images to the user, it will be appreciated that the available documents may be presented as document descriptors, which may include graphical code images. Further, although the method 700 is shown as storing graphical code images with the documents, it will be appreciated that the server device 110 may store, receive and/or transmit the document identifiers.

The method 700 begins in step 705 with a user generating a document on a client computing device 105 and instructing the server device 110 to store the document, e.g., in data storage 115. The client computing device 105 generates a graphical code image, and associates the graphical code image with the document. The client computing device 105 instructs the server device 110 to store the graphical code image in association with the document. In some embodiments, the client computing device 105 generates only the document identifier and does not generate the graphical code image. In some embodiments, another component, e.g., the server device 110, generates the graphical code image.

In step 710, the client computing device 105 sends the document to the server device 110 for storage, e.g., in the data storage 115.

In step 715, the server device 110 stores the document, e.g., in the data storage 115 in association with the user. Whether the client computing device 105 or the server device 110 generated the graphical code image, the server device 110 stores the graphical code image in association with the document.

In step 720, a user logs into the image forming apparatus 125, e.g., using the authentication process 355 to authenticate himself or herself. The image forming apparatus 125 may perform authentication by requesting a username and password, scanning of a user identification card, etc. In some embodiments, there may be no authentication.

In step 725, the image forming apparatus 125 sends a request to the server device 110 for graphical code images associated with documents that the user is authorized to access, that are available to the image forming apparatus 125, and that are authorized to be printed. In some embodiments, the request includes user-identifying information so that the server device 110 can determine which graphical code images the user and/or image forming apparatus 125 is authorized to access, receive and/or print.

In step 730, the server device 110 determines which graphical code images the user and/or image forming apparatus 125 is authorized to access, receive and/or print, and sends the graphical code images to the image forming apparatus 125.

In step 735, the image forming apparatus 125 displays a list of graphical code images. The list of graphical code images is displayed on, for example, the operation panel 305. In some embodiments, the list of the graphical code images and/or a selected graphical code image may be printed instead of displayed. One skilled in the art will recognized that the graphical code images need not be displayed as a list format. Further, different document descriptors (instead of or in addition to graphical code images) may be presented to support easier user recognition of the documents.

In step 740, the image forming apparatus 125 enables selection of one or more of the graphical code images displayed thereon.

In step 745, the user selects and captures the graphical code image of a desired document. In some embodiments, the user may use his or her mobile computing device 120 to capture a snapshot of the graphical code image. In some embodiments, the user may capture two or more graphical code images at once.

In step 750, the mobile computing device 120 requests the document associated with the selected graphical code image to be printed. In some embodiments, the mobile computing device 120 requests the document by sending the selected graphical code image to the server device 110. In some embodiments, the mobile computing device 120 may first decode the document identifier from the graphical image code, and may request the document by sending the document identifier contained within the graphical code image to the server device 110.

In step 755, the server device 110 obtains the document identifier and retrieves the document associated therewith. In some embodiments, the server device 110 receives and decodes the graphical code image into the document identifier. In some embodiments, the server device 110 receives the document identifier directly. The server device 110 sends the document to the mobile computing device 120.

In step 760, the mobile computing device 120 renders the requested document into a printable representation.

In step 765, the user, via the mobile computing device 120, issues a print request. In some embodiments, the mobile computing device 120 sends the selected document with the print request to the image forming apparatus 125 over a wireless channel. In other embodiments, the mobile computing device 120 sends the print request to the server device 110, which provides the document to the image forming apparatus 125.

In step 770, the image forming apparatus 125 generates and sends a print preview to the mobile computing device 120, in accordance with the presented embodiment. In some embodiments, the print preview may be sent to the mobile computing device over the wireless channel. In other embodiments, the print preview may be sent to the server device 110, which forwards the print preview to the mobile computing device 120. In other embodiments, the print preview may be generated by the mobile computing device 120 itself to avoid the data transfer.

In step 775, the user, via the mobile computing device 120, reviews the print preview and may edit configuration settings. If the user edits the configuration settings, the method 700 may return to step 765 to request another print preview.

In step 780, assuming that the document is ready for printing, the user, via the mobile computing device 120, submits the final print request. In some embodiments, the mobile computing device 120 sends the print request to the image forming apparatus 125 over a wireless channel.

FIG. 9 is a flow diagram illustrating a method 900 of printing a document, in accordance with a third embodiment of the present invention.

Method 900 begins with the client computing device 105 in step 905 generating the document and the graphical code image associated with the document. Although the method 900 is shown as having the client computing device 105 generating the graphical code image, it will be appreciated that another component such as the server device 110 may generate the graphical code image.

In step 910, the client computing device 105 provides the document and the graphical code image to the server device 110.

In step 915, the server device 110 stores the document and the graphical code image, possibly in a data storage 115 and/or in a print queue.

In step 920, the user, via the mobile computing device 120, captures the graphical code image, possibly by using a camera on the mobile computing device 120 to take a picture of the graphical code image displayed on a display unit 205 of the client computing device 105.

In step 925, the mobile computing device 120 provides the graphical code image to the image forming apparatus 125.

In step 945, the server device 110 provides the document to the image forming apparatus 125 for printing.

In step 950, the image forming apparatus 125 converts the document into a printable representation and prints the document.

The foregoing description of the preferred embodiments of the present invention is by way of example only, and other variations and modifications of the above-described embodiments and methods are possible in light of the foregoing teaching.

For example, in some embodiments, a graphical code image may be generated for a group of documents. For example, a graphical code image may be associated with several versions of the same document.

In some embodiments, printer configuration settings may be stored in association with each document. The print configuration settings may include color settings, duplex settings, a number of document pages to print per sheet of paper, staple settings, among other possible configuration settings.

In some embodiments, the server device 110 may store metadata associated with each document such as authorization information used to confirm user authorization to access and/or print the document.

In some embodiments, the server device 110 and/or data storage 115 may be incorporated into the image forming apparatus 125. The image forming apparatus 125 could decode graphical code images, retrieve documents associated therewith, send documents to mobile computing devices 120, and execute print jobs without accessing an external server device 110.

In some embodiments, the document identifier may be a hash code. Generating the hash code may involve inputting data representative of the graphical code image into a hashing function. The hashing function may be a one-way mapping function that maps a particular graphical code image to a unique combination of alphanumeric characters. The server device 110 may provide the graphical code image (or a portion of data extracted from the graphical code image) to the hashing function, and then compare the output of the hashing function to stored hashes.

In some embodiments, documents and/or document identifiers may be encrypted. A document and/or document identifier may be encrypted individually for a particular user. The particular user may provide authentication credentials, which may be embedded within a graphical code image. The authentication credentials may be used to decrypt the document and/or document identifier.

In some embodiments, a document may be set to expire at a certain date, time and/or event. Upon expiration, the server device 110 may be configured to delete the document from the data storage 115.

In some embodiments, the mobile computing device 120 and the image forming apparatus 125 may be connected to each other via Bluetooth or Wi-Fi Direct. This may prevent mobile computing device 120 from connecting to the same network 130 as that of the image forming apparatus 125 to increase security.

In some embodiments, the graphical code image selected by the user may be sent to the mobile computing device 120 via e-mail, SMS, or other communication process instead of via the camera.

In some embodiments, other document identifiers may be presented to the user for document selection. Upon selection of a document identifier, the graphical code image may then be presented for capture.

In some embodiments, the present invention provides a method comprising using a scanner to capture a particular graphical code image by an image forming apparatus; generating a document request in response to capturing the particular graphical code image, the document request containing a particular document identifier of a particular document; transmitting the document request to a server device, the server device configured to manage storage of documents and associated document identifiers, and configured to identify the particular document based on the particular document identifier; receiving the particular document from the server device in response to the document request; and printing a printable representation of the particular document.
